Implementations disclose methods and devices for closure control of containers. A method includes performing, by an inspection apparatus, optical 3D measuring of a closed container, the closed container comprising a closure coupled to the container; generating, by the inspection apparatus, 3D data based on the optical 3D measuring; and processing, by an evaluation device, the 3D data to determine at least one of tightness or correct seating of the closure relative to the container.

A method of inspecting packaging welds comprises the steps of creating a light beam that produces at least one light transition (t) and acquiring a raw matrix image (B(N)) covering the light transition. For each image (B(N)) obtained, a measurement of the diffusion of the light transition is stored. For each of N successive scanning increments, the raw matrix image (B(N)) is used to create an image line in which each pixel receives as its value the measurement in the raw matrix image (B(N)) of the diffusion of at least the light transition. The at least N image lines are stored in succession to obtain a matrix image and the matrix image is analyzed to determine that the weld along said fraction is in conformity when its transverse width remains, at all points, greater than a given minimum.

A device includes a camera, which captures images of moving objects, lighting units, and a controller. The camera captures recordings of the moving objects in series during transportation on the conveyor, so that a first recording of the object in a first position and a second recording of the object in a second position are obtained. The first and second positions of the object differ by the movement of the conveyor by a corresponding offset. The illumination units are composed of a dark-field illumination unit and a bright-field illumination unit, which are controlled synchronously with the camera by the controller such that the first recording generates a first contrast by a first specific control of the dark-field illumination unit and bright-field illumination unit, and in that the second recording generates a second contrast by a second specific activation of the dark-field illumination unit and bright-field illumination unit.

The camera (7) has a wide-angle lens and is configured to capture an image of an inside surface of the mouth end (202) of the parison (2) positioned in the inspection station, representing the screw thread (205) and the identification code (207) of the parison (2), shown in transparency.

A measuring apparatus is provided for inspecting a seal of an item. The measuring apparatus includes a radiation source for providing radiation for illuminating the seal of the item, a detector for receiving radiation from the item for generating a corresponding detected signal, and a processing arrangement for processing the detected signal to generate an output signal indicative of a state of the seal. The radiation source is arranged to focus the radiation into a plurality of focal points at the seal of the item, wherein the focal points are mutually spatially spaced apart. Moreover, the detector is arranged to image one or more of the focal points and to be selectively sensitive to an intensity of radiation received from the one or more focal points to generate a detected signal.

An inspection device and method for testing and inspecting integrity of a container (200) is disclosed. The inspection device has an angled member (102) and a viewing member (104) secured to the angled member. Together, the angled and viewing members are configured to hold a container to be analyzed. The inspection device also includes a cradle (106) secured to the angled member, the cradle including a cavity (108) configured to hold the angled member at an angle. The inspection device also includes a light source holder (110) secured to the viewing member, a leg member (112) extending from the light source holder, and at least one light source (114) extending through the light source holder. The light source has a first end extending outwardly from the light source holder and a second end extending within the light source holder from which light projects. The light from the light source is projected toward the viewing member. The viewing member includes at least one viewing window (105). A lens is located between the second end of the light source and the viewing member, and a filter is located between the lens and the viewing member.

An inspection device for inspecting screw-closures on bottles includes a rotationally-symmetric lens disposed above a bottle's screw-closure and having a convex portion and a flat aspheric portion, a first lighting-unit for illuminating the screw-closure, and a camera located above the lens and connected to an image processor.

The invention relates to an optical inspection station comprising: an illumination system capable of delivering a series of light beams illuminating an inspection region of the object at various angles of incidence; a camera equipped with a lens for producing images of the inspection region during rotation of the object; and a unit for analyzing and processing the images taken by the camera so as to detect the presence of reflecting defects in the images. According to the invention, the optical inspection station includes a series of optical elements for deflecting, in the air, rays reflected by the inspection region, these being placed between the inspection region and the lens so as to form, in each image, a series of views of the inspection region taken at different angles of viewing.

A vessel inspection device for examining a vessel for damage in a filling region or opening region having a bead or a bulge, which bead or bulge forms an undercut, has a camera, an objective associated with the camera, and a further optical element, which can be adjusted and fixed in place in terms of their distances from and their orientation relative to one another and relative to an image recording axis, and the optical element is a mirror in the form of a ring mirror that widens toward the camera, the longitudinal section of which, containing the image recording axis, has the form of an ellipsis portion that is inclined relative to the image recording axis and displaced radially outward, wherein the ellipsis portion has two semi-axes that deviate from one another, and the device can be moved into an inspection position relative to the vessel to be inspected for inspection of the filling region or opening region of the vessel, during every inspection procedure.
